With the rise of the unmanned retail consumption model, biometrics seems to usher in a new era. But is this biometric technology “will change the world” really safe enough? Can it be completely trusted?

Not long ago, in the "Refueling! To the Future" program broadcast by CCTV's comprehensive channel, a face recognition robot called "Small Plus" has attracted people's attention.

It is understood that the "Small Plus" robot was built by the research team of Wang Jinqiao, a researcher at the State Key Laboratory of Pattern Recognition, Institute of Automation, Chinese Academy of Sciences. According to Wang Jinqiao, in the search for lost children, the elderly, etc., "Small Plus" has won many successful cases.

In fact, biometrics, including face recognition, is more than just a high-end technology that can't be seen in TV movies. Today's biometric technology has penetrated into everyday life, and it is playing against people. Important role.

For example, Amazon AmazonGo, which started to heat up last year, and this year's Ali's unmanned supermarket, “Amoy Coffee”, the new model of unmanned retail consumption, which has been scanned and entered, has undoubtedly set off the climax of biometric technology application. In "Amoy Coffee", as long as the customer touches the face of the ordering machine, the Alipay account can be identified. Once the customer places an order, the fee will be paid immediately. Biometrics can complete this consumption process without the need for a salesperson to settle the bill.

In fact, today, when mobile payment is so current, such biometric technology is no stranger. The common Alipay has already opened the face registration function. In addition to face recognition, biometrics has been subdivided into many fields, including speech, fingerprints, voiceprints, irises, etc. Even veins and genes are expected to become one of the biometric features.

With the rapid development of science and technology, various authentication methods have also been introduced, and biometrics technology has begun to move from theory to reality, and is increasingly being applied to actual scenes, especially in the financial and security fields. According to the data of the Prospective Industry Research Institute, the global biometric identification market will be about 25 billion US dollars by 2020, and the market size of China's biometric identification industry will exceed 30 billion yuan.

Among them, fingerprint recognition, iris recognition, and voiceprint recognition will be rapidly developed in the next few years. According to the data of the China Biometrics Industry Market Research and Investment Analysis Report, the growth rate of fingerprint identification is 10.4%, accounting for 91% in the consumption field; the market share of iris recognition technology will increase from 7%. 16% by 2020; and voiceprint identification technology will mature before 2030.

But is this biometric technology called “will change the world” really safe enough?

At this year's 315 party, the face recognition of an APP was verified by the host's "changing face" camouflage, which undoubtedly gave those who were convinced of biometrics.

Despite the huge market space and bright prospects in the future, it has to be acknowledged that the current biometric technology is not yet mature. It may not only become the "culprit" of personal information disclosure, but also cause damage to human physiology.

A few days ago, some media reported that many users who used the Samsung S8 iris mobile phone felt uncomfortable after using the iris scan. In this regard, some experts have analyzed that this may be related to the over-brightness of mobile phone infrared LED lights, and from a scientific point of view, the visible spectrum is red and easily cause visual fatigue. From this point of view, iris recognition technology may not be so full of "wisdom."

However, biotechnology such as iris recognition has less impact on the human body and does not harm life. In contrast, the issue of personal information security disclosure is even more serious. For example, if the fingerprint is different, the finger will be affected by the injury or the swelling of the water, and the excessive recognition will also cause the deviation of the facial recognition.

These just allow some lawless elements to take advantage of them. "Hackers" can exploit these vulnerabilities to invade, get users' personal information, steal important files... For the various security vulnerabilities, researchers are trying to find a way to deal with them. Therefore, the popularity of biometrics technology may take some time.
